A 500 kV tower is hard to picture from a number. Stand one in front of you with your phone, at true size, in augmented reality.
Open this page on your phone to stand the tower in front of you in augmented reality. It works on most iPhones and Android phones, and there is no app to install.

New, and still being tested. If something looks wrong (the tower behind you or cut off, or the viewer won't open), tell us which phone you used.
Aviation lights. Red flashing lights on the tower tops. For structures over 200 feet, FAA guidance makes marking or lighting the default, and the FAA decides structure by structure (AC 70/7460-1N). SDG&E has not filed a design, so whether any tower on this line would carry them is not known. They are off unless you switch them on. In daylight they look faint, as real ones do.
A true-scale illustration of a typical 500 kV lattice tower, drawn about 200 feet tall. SDG&E has not filed a design; City of Temecula staff have described tower heights of roughly 125 to 191 feet (City of Temecula). It shows how big the line would look from where you stand, not where it would go: no tower positions have been filed, so wherever you place it is your choice, not a prediction. A sign in the scene says so in every screenshot.
